创建表空间

CREATE TABLESPACE NNC_DATA01 DATAFILE 'D:\NCData\nnc_data01.dbf' SIZE 500M AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K ;
CREATE TABLESPACE NNC_INDEX01 DATAFILE 'D:\NCData\nnc_index01.dbf' SIZE 500M AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K ;
CREATE TABLESPACE NNC_DATA02 DATAFILE 'D:\NCData\nnc_data02.dbf' SIZE 500M AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K ;
CREATE TABLESPACE NNC_INDEX02 DATAFILE 'D:\NCData\nnc_index02.dbf' SIZE 500M AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K ;
CREATE TABLESPACE NNC_DATA03 DATAFILE 'D:\NCData\nnc_data03.dbf' SIZE 500M AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K ;
CREATE TABLESPACE NNC_INDEX03 DATAFILE 'D:\NCData\nnc_index03.dbf' SIZE 500M AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K ;

创建用户

create user nc57 identified by jxnc57 default tablespace nnc_data01 temporary tablespace temp;

用户授权

grant connect,dba to nc57;

创建虚拟目录

create or replace directory PATH as '/impdp';

在ORACLE_HOME的bin目录下执行导入操作

table_exists_action选项：

• skip 是如果已存在表，则跳过并处理下一个对象
• append是为表增加数据
• 是截断表，然后为其增加新数据
• replace是删除已存在表，重新建表并追加数据

impdp nc57/jxnc57 directory=PATH dumpfile=jxkh20191209.dmp logfile=jxkh.log schemas=nc57 table_exists_action=truncate

导出

expdp nc57/jxnc57 schemas=nc57 dumpfile=jxkh.dmp directory=PATH;
